Addition of the A- and B-subunits before and after ultrasonic minimally affected SLP secondary structure. A-subunit addition before ultrasonic negligibly affected SLP tertiary structure. Addition of the B-subunit after ultrasonic reduced hydrophobic thermal aggregation.

Microscopic improvement resulted in increased encapsulated water within interstitial spaces of the A-SLP gel matrix. This enhanced water mobility in B-SLP gels, in turn weakening gel stability. The changes observed in B-SLP were primarily due to reduced hydrophobic interactions between the proteins.

In this investigation, an innovative approach termed Ultrasonic-Rotating Extrusion-Wire Arc Additive Manufacturing (U-RE-WAAM) was proposed, which integrates the synergistic effects of ultrasonic and mechanical force fields into the WAAM process. Comparative analysis were conducted on defects, microstructure and mechanical properties between WAAM and U-RE-WAAM samples to investigate the impact of U-RE-WAAM on aluminum alloy samples. The results show that the mechanical force field causes a large amount of plastic deformation, which refines the grain size and restructures the precipitation phase from clustered aggregates to a fine dispersion.
